Sujiko vs Ikura: Salmon Roe in Japanese Cuisine

In Japanese cuisine, “Ikura (いくら)” is made out of manure salmon roe or trout roe that’s been pickled typically in soy sauce.

The orange caviar comes in individual-shaped spherical balls and is well-known as a Sushi or Onigiri ingredient.

As you may know, in addition to Ikura, there is one more Japanese food delicacy made of salmon roe or trout roe, which is called “Sujiko (筋子)”.

Sujiko is quite similar to Ikura, but what is the difference between them?

Sujiko vs Ikura: What is the Difference?

As you can see in the picture above, Sujiko has a dark reddish color compared to Ikura.

Since Sujiko is made of a skein of immature salmon roe or trout roe surrounded by the ovarian membrane, each egg is slightly smaller than Ikura.

While Ikura is usually pickled in soy sauce, Sujiko is often brined, which prevents its shape from easily collapsing.

In other words, if the small immature egg isn’t salted, it is fragile compared to Ikura.

As for the use of the Sujiko roe, unlike Ikura, it is rarely used as a Sushi topping mainly because it is within the egg sac.

But as with Ikura, the dark reddish roe is often used in Onigiri rice balls.

Summary

Lastly, to make it easier for you to understand the difference between Ikura and Sujiko, here is the comparison table.
